A curved structure for a work vehicle includes a first curved support extending a length, a second curved support extending a length, the second curved support spaced apart a width from the first curved support, and a curved windshield positioned between and connected to the first and second curved supports.

A work vehicle includes a vehicle body to which work instrument is connected at a back, and a ROPS frame erected at a back portion of a driver seat area in the vehicle body. The work vehicle further includes a positioning unit configured to detect a position of the vehicle body based on a signal sent from a positioning satellite, and a support unit that is fixed to an upper portion of the ROPS frame and supports the positioning unit from below. The positioning unit has a harness connection portion that is connected to a harness for sending information to outside. The harness connection portion is located at a back portion of the positioning unit. The support unit is located protruding backwardly from the harness connection portion of the positioning unit.

A work vehicle includes a front wheel unit and a rear wheel unit attached to a vehicle body frame, a power source mounted at a rear portion of the vehicle body frame, a ROPS bracket fixed to the vehicle body frame at a region thereof forwardly of the power source and a ROPS. this ROPS includes a pair of left and right upright portions and a crossbar connecting the upright portions at upper portions thereof. Lower end portions of the pair of upright portions are supported to the ROPS bracket to be pivotable toward the power source about a horizontal axis extending in a vehicle-body transverse direction.

Aspects hereof relate to a lever-actuated operator protection apparatus. In some aspects, the lever-actuated operator protection apparatus can be raised and lowered by an operator from a seated position, for example, on a terrain working vehicle.

In a work vehicle, a safety frame includes a base, a pair of left and right lower frames extending from the base and fastened to a pair of left and right rear wheel fenders, and an upper frame having an inverted U shape connecting upper portions of the pair of left and right lower frames. The base is removably fastened to a rear axle case. A length in a width direction between a pair of left and right rear wheels is changed by changing a length in a width direction of the upper frame and changing a fastening position of the base to the rear axle case.

A carrying system releasably engages with the rollover frame of a tractor. The system includes a header sleeve connected to the rollover frame's crossbar, at least two lateral sleeves, and at least one of those lateral sleeves engaged with each of the rollover frame's two vertical supports. The header sleeve acts as an anchor and includes straps which releasably engage the lateral sleeves. The lateral sleeves include at least one attachment site, such as a D-ring, which facilitate the releasable connection of items such as tools in a myriad of configurations. Alternative embodiments include a suspended pouch for holding smaller items; more than one lateral sleeve per side in a daisy chain configuration; and an anchor strap so the carrying system can be used on rollover frames that are hinged and in the folded position.

A rollover protection apparatus unlocks and lowers from a raised position to a lowered position suitable for clearing a low hanging obstacle when an operator applies a force to an operator lever or pedal. The rollover protection apparatus returns to the raised position when the operator ceases applying force to the operator lever or pedal.

A rollover protection structure (ROPS) for a work machine includes a rigid strut having a fixed longitudinal length. On one end of the strut, a pivot end mechanism is attached that has a mounting plate that pivots relative to the strut. On the opposite end of the strut, a jack end mechanism is attached that has a mounting plate that extends longitudinally relative to the strut. When installed, e.g., with the mounting plate on each end of the strut being affixed to the work machine such as by welding, the ROPS can be extended to span an opening in the chassis of the work machine and to impart specific compression/tension on the strut. Moreover, the jack end mechanism can be disassembled, while its mounting plate remains affixed to the work machine, and the strut can be rotated about an axis in pivot end mechanism about which the mounting plate therein pivots.

A operator protection apparatus unlocks and lowers from a raised position to a lowered position suitable for clearing a low hanging obstacle when an operator applies a force to an operator lever or pedal. The operator protection apparatus returns to the raised position when the operator ceases applying force to the operator lever or pedal.

The present disclosure achieves a cabin-protection structure and a tractor, each of which has improved usability. Provided is a cabin-protection structure (30) for a tractor (1). The tractor (1) includes: a cabin framework (50) that defines a cabin (12) containing an operation device; a roof (20) provided above the cabin framework (50). The cabin-protection structure (30) is provided above the roof (20).
